Abstract

FIELD: construction.

SUBSTANCE: equipment comprises a polymer mould with side walls and a bottom and a template made with the possibility of installation inside the mould and having side walls, external dimensions of which correspond to internal dimensions of side walls of the mould, and at least one partition between them to create compartments. The method to manufacture multicoloured tiles consists in the fact that the cement-sand mixture is laid into the mould in layers, first forming the face layer of the tile by filling the appropriate compartments of the template installed in the mould, to the specified height, with cement-sand mixtures of different colours. Then the template is taken out from the mould, and the bearing layer of the tile is formed by filling of the remaining part of the mould with a one-colour cement-sand mixture, afterwards the mould with the cement-sand mixture is exposed to vibration effect with subsequent hardening of this mixture, and the finished product is extracted from the mould.

EFFECT: invention will make it possible to simplify equipment design and to reduce labour intensiveness of the process for manufacturing of multicoloured tiles.

Description

The group of inventions relates to the construction industry, in particular to the equipment of equipment for molding by vibrocasting of paving, floor and facing tiles from multi-color sand-cement mortars, and a method for manufacturing such products.

A known method of mosaic multi-color flooring, in which using glass or aluminum veins (partitions), laid according to a given pattern and filled with colored sand-cement mortars, get a multi-colored floor with a pattern. Veins (partitions) can remain in the floor or be removed before final processing after hardening of the mortars (V.I. Malin. Handbook of a young tiler and mosaic. M .: Higher school, 1988, p.167).

The known method is characterized by great complexity and is unsuitable for the manufacture of tiles.

A known pallet for vibropressing paving slabs with a relief image, consisting of a bearing metal sheet with a thermoplastic coating on its forming surface having a relief image. On this coating, rectangular grooves or trapezoidal protrusions are made that are in close contact with the partitions of the device separating the colored molding sand (description of the invention to patent RU 2358862, class B28B 3/00, published on June 20, 2009).

In a known solution, paving slabs are obtained by vibrocompression, rather than vibration casting, as in the proposed invention, and taking into account the use of other equipment (vibropress), its equipment may not be suitable for use in vibration molding, moreover, the design of this device is not described in the named source.

The technical result of the invention consists in expanding the range of paving, floor and facing tiles, as well as simplifying equipment and reducing the complexity of the manufacturing process of multicolor tiles.

The named technical result is achieved in the invention due to the following set of features.

Equipment for the manufacture of multi-colored tiles consists of a mold designed for pouring a sand-cement mixture and traditionally used for the manufacture of tiles. This form has side walls and a bottom. Along with the above-mentioned mold, the proposed snap-in includes a template made with the possibility of installation inside the mold and having side walls whose external dimensions correspond to the internal dimensions of the side walls of the mold and at least one partition between the side walls of the template to form compartments. One or more partitions made with the possibility of tight fit to the bottom of the form. The side walls of the mold and, respectively, of the template, as well as the partition, can have any configuration in accordance with the plan of the manufacturer and / or customer.

The mold is made of polymeric material, and the template is made of metal.

A method of manufacturing a multi-colored tile is that it uses the above-described equipment, while laying the sand-cement mixture in the mold is carried out in layers, first forming the front layer of the tile by filling the appropriate compartments of the template installed in the mold to a predetermined height with different types of sand-cement mixes flowers. Then the template is removed from the mold and the supporting (back) layer of the tile is formed by filling the remaining part of the mold with a single-color sand-cement mixture. After that, the mold filled with a sand-cement mixture is subjected to vibration, followed by hardening of this mixture. For this mold with the mixture, the time necessary for setting the mixture to set on the racks is maintained, after which the finished product is removed from the mold.

The front layer of the tile is formed to a height not exceeding one third of the height of the mold wall. This is dictated by economic considerations, since expensive white cement is used to prepare a colored sand-cement mixture.

The invention is illustrated by drawings, figure 1 schematically shows the equipment for the manufacture of tiles; figure 2 is a form with a template inside it, the compartments of which are filled with molding mixtures of different colors (sectional view).

As can be seen in figure 1, the snap consists of a mold 1 made of a polymeric material (low density polyethylene) and containing side walls 2 and a bottom 3, as well as a template 4 made of metal (iron, aluminum) containing side walls 5 and at least one partition 6. The height of the side walls 5 and partitions 6 of the template 4 corresponds to the height of the side walls of the mold 1. The pattern 4 is configured to be installed inside the mold 1 without a gap between their side walls.

A method of manufacturing multi-colored tiles consists in the fact that first they prepare the equipment by placing each template 4 inside each form 1. The template, thanks to one or more partitions 6, divides each form into a predetermined number of compartments 7 and 8. Each compartment is approximately one third of the height of the wall 2 of the form filled with a sand-cement mixture of 9 and 10 of the corresponding color.

After filling each form with colored sand-cement mixtures, the template 4 is removed from form 1, and the remaining two-thirds of the height of the wall of the form is filled with the usual gray-cement mixture of gray color, thereby forming the supporting side of the tile (not shown).

Further operations are carried out according to standard technology, namely, the molds completely filled with the sand-cement mixture are fed to the vibrating table and the mixture is compacted for 5-10 s. After that, the molds with compacted sand-cement mixture are placed on the rack and put on the platform to set the mixture with the necessary strength.

After a mixture of strength, the finished products are removed from the mold, placed on transport pallets and sent to the consumer.
